Bypass SodaLake road on an FJR.. Keep heading west on 58 then turn right (north) on Bitterwater road. The vistas are better, the road is twistier, the passes and views are higher and better. It's open range so keep your eyes open for Mr. Bull and Mrs. Cow. Rode that road this morning and saw a herd of gazelle looking creatures. Clocked them at just under 50. Bitterwater road will eventually take you back to highway 41/46, just south of the James Dean memorial. Bitterwater is half marked, half unmarked e.g. no centerstripe. The ride this AM there were zero, nada, zip vehicles on it except me. Leave SodaLake for O'vale and his new dualsport...
Not to say the road is not passable on the FJ, just that you stand a fair to good chance of doing cosmetic damage. Some don't care, some do.
This is just one of what used to be my secret backroads. No worries, I have many others.
